Chloroplasts most likely originated from the endosymbiosis of cyanobacterial ancestors,entering the eukaryotic lineage about 1.0-1.5 billion years ago(Parfrey et al.,2011;Archibald,2015).Consequently,their biogenesis depends on genetic information from both the nuclear and chloroplast *** housekeeping genes of core components in photosystemsⅠandⅡ(PsI and PsII)are encoded by the plastid genome。

This paper discusses a specific phase in the history of south Asia --c.2000-500 BCE--and on that basis highlights the importance of constructing the history of non-urban,non-literate cultures that usually stand outside the ambit of the historian’s notion of *** main methodological argument concerns the relationship between history and archaeology.
